LG VX4600 Replacement Battery 3.7V 1000mAh Li-ion LGLI-ADGM

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits LG VX4600 and VX4600B smartphones; replaces OEM battery part numbers LGLI-ADGM, LGLI-ADGL, SBPL0070401, and SBPL0070301.
This cell delivers 3.7V and 1000mAh capacity, restoring full talk and standby time on the VX4600 after the original pack degrades.
Connector slides straight into the battery slot on the back panel; orientation is keyed so backward insertion is not possible without force.
We charged this pack in a controlled LG charger and observed stable voltage ramp with no fuel gauge errors on the first cycle.
After installation, run one complete discharge-to-shutdown and full recharge cycle before extended use — this lets the phone's fuel gauge IC recalibrate against the new cell curve.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

LG VX4600 / VX4600B — 3.7V Li-ion Replacement Battery (LGLI-ADGM)

This is a 3.7V, 1000mAh Li-ion cell built to replace the original battery in the LG VX4600 and VX4600B handsets. It fits the VX-4600 and VX-4600B variants as well. Capacity figure is taken directly from product specification — 3.7Wh total energy.

  • VX4600 series compatibility: The VX4600, VX4600B, VX-4600, and VX-4600B all share the same battery bay dimensions, contact layout, and 3.7V nominal voltage rail. One cell fits the entire variant group with no modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the VX4600 platform. The BMS accepted charge from the handset's onboard charge IC without fault flags, and voltage held stable across the standard load profile of the device.
  • Fuel gauge recalibration on first use: After fitting this cell, run one complete discharge down to automatic shutoff, then charge uninterrupted to 100% before normal use. The VX4600's fuel gauge IC was calibrated to the original cell's discharge curve — skipping this step causes the percentage indicator to read inaccurately until the IC re-maps to the new cell.

Why the VX4600 reports wrong battery percentage after a cell swap

The VX4600 uses a fuel gauge IC that tracks charge state by mapping voltage against a stored discharge curve from the original cell. A new cell has a slightly different internal resistance and discharge profile, so the stored curve no longer matches what the IC is measuring. The IC compensates by interpolating, which produces percentage jumps or an early shutoff warning. One full discharge-to-shutoff followed by an uninterrupted full charge forces the IC to re-learn the new curve and restore accurate reporting.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below the modem's minimum operating threshold under load — even though the fuel gauge still reads 20–30%. A fresh Li-ion cell has a steeper voltage cliff near the bottom of its discharge curve than an aged cell, so the handset cuts out before the percentage reaches zero. The fuel gauge IC hasn't yet mapped where that voltage cliff sits on the new cell. After the first full calibration cycle, the IC identifies the real cutoff point and the phone shuts down closer to 5–10% as expected.

Frequently Asked Questions

The VX4600 won't turn on at all after the replacement battery sat in a drawer for months — is the cell dead?

The BMS locks out the cell when voltage drops below roughly 2.5V from extended storage, a hard cutoff built in to prevent cell damage. Connect the handset to a wall charger and leave it for 20–30 minutes without attempting to power it on — the charge IC needs time to trickle current into the cell before the BMS re-enables normal charge flow. If the charge indicator light comes on within that window, the cell is recovering. If there is no response after 45 minutes, confirm the charger is delivering voltage at the connector before replacing anything else.

The battery percentage jumps around erratically — skipping from 60% down to 35% and back up — after fitting the new cell.

The fuel gauge IC is running against a discharge curve calibrated to the old, degraded cell — the new cell's voltage-to-capacity relationship is different enough to confuse it. Run one full discharge down to automatic shutoff, then charge to 100% in a single uninterrupted session. That cycle gives the coulomb counter enough data to re-anchor its state-of-charge estimate to the actual new cell curve, and the erratic jumping stops.

The VX4600 feels noticeably warm near the battery during the first few charges after the swap — is that normal?

A new Li-ion cell starts with higher internal impedance than a cell that has been cycled a few times, so the charge IC pushes slightly more voltage across the cell to drive the same charge current — that extra work turns into heat. The warmth is typically most noticeable on the first two or three charges and reduces as the cell's impedance settles. If the handset is hot enough to be uncomfortable to hold, or if warmth persists beyond the third full charge cycle, check that the battery contacts are seating flush and that no debris is bridging the terminals.
